Answer:

Two other algebraic expressions based on this situation are:

J = m-2

B = \frac{m}{2}

Step-by-step explanation:

Let m represent Meg's age.

Jill is 2 years younger than Meg.

Let J represents Jill's age

Jill's age J = m-2

Beth is half as old as Meg

Let B represents Beth's age

Beth's ageB = \frac{m}{2}

So,  two other algebraic expressions based on this situation are:

J = m-2

B = \frac{m}{2}

As Sales Manager for ISeeYou Productions, you are planning to review the prices you charge clients for television advertisement
aksik [14]

The development fee p can be modeled by the equation p=-400q+9600 where p is the price the company charges and q is the number of contracts they get. The total revenue R ISeeYou obtains by signing q contracts is found by using the function: R(q)=-400q^{2}+9600q. The cost ISeeYou Productions can be found by using the following function: C(q)=800q+16000. The monthlhy profit of Express ISeeYou Productions if found with the next function: P(q)=-400p^{2}+8800q-16000. ISeeYou should sign 2 or 20 contracts to break even.

a) In order to solve part a of the problem, we will suppose the price will have a linear relation with the amount of contracts they signed, so we need to find two points to build this function.

We know that when signing 6 contracts, the company charges $7,200, so our first point will be:

(6, 7200)

we also know that the company signs 14 contracts when they charge $4,000. So our second point is:

(14, 4000)

so we can use these points to find the slope of the line by using the

slope formula:

m=\frac{p_{2}-p_{1}}{q_{2}-q_{1}}

m=\frac{4000-7200}{14-6}

so the slope is:

m=-400

We can now use one of those points and the slope to find the function for the price, so we get:

y-y_{1}=m(x-x_{1})

p-p_{1}=m(q-q_{1})

if we used the point: (6, 7200) we get:

p-7200=-400(q-6)

which can now be simplified:

p=-400q+2400+7200

so the price function is:

p=-400q+9600

b) In order to find the revenue equation we need to multiply the price equation by the amount of contracts they signed in a month, so we get:

R(q)=pq

R(q)=(-400q+9600)q

R(q)=-400q^{2}+9600q

c) The cost can be found by adding the fixed cost and the variable cost, so we get:

C(q)=800q+16000

d) The profit is found by subtracting the montly cost from the monthly revenue, so we get:

P(q)=R(q)-C(q)

so

P(q)=-400q^{2}+9600q-(800q+16000)

so we can now simplify our function to get:

P(q)=-400q^{2}+9600q-800q-16000

P(q)=-400q^{2}+8800q-16000

e) In order to find the number of contracts for the company to break even, we need to find the q contracts that will give a profit of $0 so we set the function of the previous part of the problem equal to zero so we get:

P(q)=-400q^{2}+8800q-16000

-400q^{2}+8800q-16000=0

we can start by factoring a -400 from the left side so we get:

-400(q^{2}-22q+40)=0

we can divide both sides of the equation into -400 to simplify the equation so we get:

q^{2}-22q+40=0

and now we can factor the left side of the equation to get:

(q-20)(q-2)=0

we can now split this into two equations to get:

q-2=0    and   q-20=0

so our two answers are:

q=2 and q=20

the company will break even when signing 2 and 20 contracts.

In the attached picture you will be able to see the break even points on the graph of revenue and cost.
